Patent GB-466524-A (GB)
Title: Improvements in the manufacture and production of heavy oils poor in or free from asphalt
IPC: C10G21/00
Filed: 1936-01-20
Abstract: Heavy oils free from asphalt are obtained by subjecting the products obtained from solid carbonaceous materials by extraction under pressure or mild destructive hydrogenation after removal of non fusible constituents, to an extraction treatment with light aliphatic hydrocarbons containing from four to seven carbon atoms in the molecule, separating from each other the oil and asphaltic layers thus formed, distilling off solvent from the oily layer and separating the latter by distillation into fractions of different boiling ranges, mixing the lower boiling fraction with the asphaltic layer and employing the mixture as pasting medium for a fresh charge of initial material.  The extraction process is carried out by subjecting the solid material mixed with a middle oil and asphaltic products from a prior treatment to temperatures of 300 to 450 DEG C., preferably in stages of increasing pressure from 50 atmos. upwards while the mild destructive hydrogenation is carried out under similar conditions but with a high partial pressure of hydrogen.  The usual catalysts may be used in both treatments.  The products are freed from solids by filtration or centrifuging and are then extracted in a closed vessel at 20--200 DEG  C., with butane, pentane, hexane, &c., or a benzine of similar boiling point.  The extraction is preferably carried out at about the critical temperature of the extracting agent.  A preliminary extraction with normally gaseous hydrocarbons may be made.  The oils are separated from the precipitated asphalts and the solvent removed.  The oil is then separated by distillation into a middle oil fraction boiling up to about 350 DEG  C., which is mixed with the asphalt to serve as pasting agent for fresh material and a heavy oil from which a good lubricating oil can be obtained by treatment with hydrogen in presence of catalysts at 250--475 DEG  C. under 100--300 atmos. pressure.

Abstract: 271,534. Woods, M. W., Woods, M. G., Keith, J. P., Cruwys, J., Richardson, G., and Power Equipment Co., Ltd. Jan. 22, 1926. Commutator switching-arrangements. - Converting apparatus comprising a synchronous motor and a rectifying commutator or a d.c. generator is started by an a.c. motor through an automatic switch connecting it in circuit for a predetermined relatively short period. The switch may be controlled by clockwork or the equivalent but is preferably thermostatically controlled. A bimetallic strip 16 with a heating coil 20 and controlling magnets 18, 19 operating upon an iron armature 17 is heated when a switch 23 isclosed to start a series repulsion starting motor- 12, contacts 21, 22, the motor circuit being held closed by the magnet 18. The magnet 19 is also energized and effects a quick break at the contacts 21, 22 to stop the starting motor and disconnect the heating coil 20 when the strip is sufficiently heated; it also holds the switch in the open position so long as the switch 23 remains closed. The magnets 18 19, may be energized from the d.c. side. Adjustment of the period of operation may be made by moving the magnet. The plant employed in the arrangement according to Fig. 1 comprises a synchronous motor the rotor 4 of which is supplied by an auxiliary commutator 5 and secondary winding 6 from the transformer 7. This transformer also supplies current through a main rectifying commutator 8 for charging,a battery 31. In order that this battery may be connected correctly a relay armature 40 is polarized by the battery 31 through a switch 24, linked with the starting control element 16, when the starting motor is switched out. At the same time a magnet 32 is polarized by the auxiliary commutator 5 through a switch 26 also linked to the element 16. In consequence the appropriate one of two contactors 45, 46 is energized to connect correctly the battery and main commutator 8. Fig. 5 shows the thermostatic switch and the bimetallic strip 16 carrying its armature 17, a brass block contact 21 and a carbon contact 21<a>. A spring 29 behind the strip 16 carries an insulating block 28 which operates the switch blade 24 to close the polarizing circuit or blade 25. The polarized relay is shown in Fig. 6 and comprises a T-shaped armature 37 the depending leg of which lies in the polarizing coil 30. The armature is pivoted at 40<a> to give it a slow period and hunting is prevented by bifurcating the spring contact tongue 28 and placing a fixed pin 39 between its arms. The armature 37 co-operates with the poles 33, 34 of the magnet which is energized by the rectified impulses.

Abstract: 1521351 Measuring displacement photoelectrically NATIONAL RESEARCH DEVELOPMENT CORP 6 Jan 1977 [19 Jan 1976] 02057/76 Heading G1A The position of a surface 1,1', Figs. 1 and 2, is measured by: illuminating the surface 1,1' with an array 4 of spaced sheets of light; imaging, 12, the surface on a photo-detector 13 (PIN diode or photo-multiplier) having a field of view so dimensioned as to give a variable output if the imaged sheets move relative to the detector; shifting the sheets 4 cyclically to cause the detector output to include a sinusoidal component whose phase represents the position of the surface 1, 1'; and using the phase as a measure of the surface position. Components of a beam from a laser 5, split at 6, are redirected by mirrors 7, 10 so angled that the components emerge from the splitter at a small angle to each other, where by the composite beam comprises an array of fringes forming  parallel uniformly-spaced sheets of light. These, magnified if necessary by a telescope 8, 11 are directed to the surface 1, 1' at a substantial angle to a measuring axis defined by the lens 12 and detector 13. Lateral oscillation of the sheets is provided by modulating the phase of at least one constituent beam with a Pockels cell 9 driven by a ramp generator 14 which also supplies signals to phase detectors 16, 17 arranged to feed pulses representing the direction and magnitude of surface movement to an up/down counter 20. The oscillation amplitude of the light-sheets is an integral number of sheet spaces, preferably one. The photo-detector may have a number of sensitive areas spaced in conformity with the light sheets. Both constituent beams may be modulated at high frequencies, so as to cause the light sheets to oscillate at a difference frequency.
